摘要
An alternate formulation is derived for predicting acoustic radiation from a vibrating object in an unbounded fluid medium. The radiated acoustic pressure is shown to be expressible as a surface integral of the particle velocity, which is determinable by using a non- intrusive laser Doppler velocimeter. Solutions thus obtained are unique. Moreover, the efficiency of numerical computations is high because the surface integration can be readily implemented numerically by using the standard Gaussian quadratures. This alternate formulation can be desirable for analyzing the acoustic and vibration responses of a lightweight, a flexible or a structure with a hostile environment for which a non- intrusive laser measurement technique must be used.
